Skeletal muscle index (SMI), as an effective indicator of nutritional status, plays an important role in the prognosis of malignancy. However, the impact of skeletal muscle changes on tumor prognosis has not been systematically elaborated. We aimed to explore the value of skeletal muscle changes in the prognosis of distal cholangiocarcinoma (DCC) patients undergone pancreaticoduodenectomy (PD).

Imaging the entire cardiomyocyte network in entire small animal hearts at single cell resolution is a formidable challenge. Optical microscopy provides sufficient contrast and resolution in 2d, however fails to deliver non-destructive 3d reconstructions with isotropic resolution. It requires several invasive preparation steps, which introduce structural artefacts, namely dehydration, physical slicing and staining, or for the case of light sheet microscopy also clearing of the tissue.

Acquired Diaphragmatic Hernia and Intestinal Obstruction in a Child with Methylmalonic Acidemia Following Pediatric Liver Transplantation.

Transplant Proc

January 2025

Pediatric Intensive Care Unit, Guangzhou Women and Children's Medical Center, Guangzhou Medical University, Guangzhou, China. Electronic address:

Background: An acquired diaphragmatic hernia (ADH) is an uncommon event following pediatric liver transplantation. Pediatric liver transplantation proves effective in prolonging survival and improving quality of life for children with methylmalonic acidemia. Remarkably, there have been no previous reports documenting the occurrence of post-liver transplant ADH in patients diagnosed with methylmalonic acidemia.

Background: Spirometry-based assessment of pulmonary function has limitations in detecting pulmonary toxicity following cancer treatment with chemotherapy, haematopoietic stem cell transplantation, radiotherapy or thoracic surgery. Nitrogen single and multiple breath washout tests are sensitive in assessing peripheral airway function, and lung imaging detects structural abnormalities, but little is known about their use in paediatric cancer patients and survivors. We aimed to 1) identify studies using nitrogen single or multiple breath washout tests and/or lung imaging to assess pulmonary toxicity in paediatric cancer patients and survivors, and 2) describe reported abnormalities.
